8 Claims.

This invention relates to water bags, and more particularly to areceptacle designed to be watertight which may be employed as a hotwater bag, but which will at the same time have a neck or mouth ofsufiicient size so that the receptacle may readily be filled with piecesof ice, and which will be provided with a connection for a syringe tubeso that it may also be used as a syringe. Certain features of ourinvention, however, are desirable for use in devices for one or more ofthe purposes above named, and are not necessarily restricted to a bag orreceptacle which is used for all of the three stated objects.

It is more or less common to combine a hot water bag and syringe into asingle device, that is, to provide a rubber bag or similar receptaclewith a filling opening which may be closed against leakage, and alsowith a connection for a syringe tube which may also be closed when it isdesired to use the device as a hot water bottle. However, such areceptacle has not been well adapted for use as an ice bag, owing to thefact that the filling opening is usually of relatively small size andwill not receive sufliciently large pieces of ice. If the fillingopening was of large size, difilculty was encountered in closing thisopening tightly against leakage, or, if a screw plug was employed, thebag would be unwieldy and awkward or uncomfortable to use.

The present invention, however, has for one of its objects the provisionof a three-in-one receptacle which may be used as a hot water bag, as anice bag, or as the receptacle for a fountain syringe.

Another object of the invention is the provision of a receptacle formedof waterproof material so that it may contain water, which is providedwith a relatively large filling neck through which cracked ice may beinserted, and which also embodies means for effectively closing saidfilling neck when the bag or receptacle is in use to prevent leakage ofthe contents.

Another object of the invention is the provision of a bag or receptacleof the character described, which is provided with a filling neck ofrelatively large size and of flexible material, whereby this neck may befolded within the outline of the receptacle itself and the latter closedover the neck to conceal the neck from view.

Another object of the invention is the provision of a water-tightreceptacle which when closed will have a smooth exterior outline, andwill be provided with no projecting necks or tabs such water bottles.

A still further object of the invention is the provision of awater-tight receptacle having a filling neck, and means for closing saidneck against leakage, and also being provided with a secondary closurewithin which the neck may be contained, so that the latter is concealedand lies within the regular outline of the receptacle when the secondaryclosure is in closed position.

To these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

Fig. 11 is an enlarged section on line I I--ll of Fig; 1.

To illustrate a preferred embodiment of our invention, we have shown awaterproof bag or receptacle l0 which maybe and preferably is made ofrubber, as is usual with hot water bags of this character. As shown, forexample, in Figs. 4, '7 and 8, the bag I0 is open across its entire top.and for a short distance down each side. At the edges formed by thisopening a fastening means is provided to secure the edges together. Asshown, this means may be in the form of the ordinary zippers or hooklessfasteners H, which may be mounted upon tapes i2, the tapes in turn beingsecured to the rubber walls of the bag. The usual slider I 3 is providedto effect the opening and closing of the fasteners.

The closure just described may be termed the secondary closure of thereceptacle, as this does not form the water-tight or leak-proof closurefor the watercontaining portion of the device. That closure will,however, now bedescribed. A

' filler neck It is provided whiclfle'ads into the inthe filling neck IIwhen the latter is in the posisecured to the wall by the projectingpartition portions I1 and I8, shown more particularly in Fig. 7.

It will be seen with reference to Fig. 4 that the neck I4 is relativelylong, and when in extended position, as when it is ready for filling, asshown in Figs. 4 and 5,'projects from the opening at the upper end ofthe receptacle III through the closure II. This neck forms the primaryclosure of the water-tight receptacle, and, as wil be hereinafterexplained, is of flexible material and adapted to be folded or rolledandtucked within the upper portion of the bag l so that it will not onlybe leak-proof but will be concealed from sight.

It will be noted, of course, that thelower end of the neck I 4 is somedistance below the upper end of the bag l0, so that considerable spaceis provided between the shoulders or projections l1 and [8, as shown inFig. 7, and the top closure of'the bag, thus providing a space in theform of a pocket within which the neck Il may be disposed when folded.In order that the folding operation may be effected conveniently. and inorder that it may be locked in place after being folded, a lock bar isprovided which is shown more especially in Fig. 9. This lock barconsists of a pair of end members ['9 and 20 provided with angularlydisposed portions 2| and 22 forming hooks in connection with theportions I9 and 20.

The members Ill-and 20 are joined by a fiat bar 23, and also extendingbetween them is a rod 24 which may be inserted through a tubular boss 25carried upon the side of the neck It. This rod may be conveniently pasedthrough the boss or sleeve 25, and thereafter secured by rivetingto themembers I! and 20 in order to secure the lock bar to the neck. Theposition of the lock bar when secured in place is shown in Fig. 2, fromwhich it will be seen. that the bar 23 rests against the wall of theneck above the tubular boss or sleeve 25, and that the end members I 9and 20 lie just beyond the side edges of the neck H, as the length ofthe bar 23 and rod 24 correspond substantially with the width of thefilling neck.

0n the inner surface of the walls of the receptacle l0 adjacent theupper end thereof and within the space above the: members l and IS apair of hooks or catch members 26 are provided, these members beingpreferably formed of rubber and being molded upon the wall of the bag orreceptacle III, which is of the same material. As shown in Fig. 4. oneof these hooks or catch members is provided adjacent each side edge ofthe bag. Upon the opposite wall of the bag and located substantiallyopposite but slightly above the members 28 are a pair of stop members21, which may also bev molded integrally with the bag wall. The members26 and 21 are designed to cooperate with the lock members 19 and 20 tohold the neck in closed position within the mouth of the receptacle andbelow the closure I2.

The bag is filled with water or ice through tion shown in Figs. 2, 4 and5. It being desired to close the bag, the members I! and 20 are graspedbetween the fingers and the lock bar is turned downwardly away from theobserver, as

shown in Fig. 2, or to the right, as shown in,

Fig. 5, so as to roll or fold up the flexible neck l4. As shown, it isdesigned that the lock bar be given one and a half complete turns, orthree half turns, at the end of which movement the neck will be foldedor rolled into the position shown in Figs. 7 and 8, and the hook membersoriginally at the upper edges of the members I! .and 20 will lie inreverse position at the lower edges of these members. so as to engagebelow the hooks or catch members 28, as shown in Fig. 8. The upper endsof the members I! and 20, as

"--.shown in this figure, will abut against the stops 21, and thus thismember will be eflectively held in position and the neck M will beprevented from unrolling. The walls of the neck will be tightly pressedtogether in this position so that there will be no danger of leakageregardless of the position in which the bag may be, and the folded neck.as apparent from Figs. 7 and 8, will lie within the upper portion of thereceptacle below the closure I2, so that the latter may be closed andthe folded neck completely concealed from view. The bag willthen havethe appearance shown in Figs.'1 and 6.

In order that our device may be employed as a fountain syringe aswell asa hot water bag and ice bag, we have provided in one of the walls ameans for connection with a tube, which connection will lead to theinterior or chamber of the bag. As one means of accomplishing thisresult, there is formed upon one of the walls of the bag, and in thisinstance adjacent the upper end thereof, a valve housing '28 withinwhich is mounted a valve plug 29. This plug is provided with a laterallyextending flange 30 adapted to seat in a corresponding recess in thebody 28 to hold the plug in place, and is also provided with an opening3| extending inwardly from the exterior thereof part way through thevalve body. From the bottom of this opening to the inner end, the valvemember is split longitudinally into two parts, as shown at 32.

A nipple member 33, connected at the end of a rubber syringe tube 34 ofthe usual form, is designed to be inserted through the opening 3! andbetween the inner portions of the valve 23 through the split 32. Asshown, for example in Fig. 10, this will cause the inner end portions ofthe valve member to be spread apart so that the nipple 33 willcommunicate with the interior of the receptacle. As will also beapparent from Fig. 7, when the nipple is withdrawn, the portions of thevalve body on opposite sides of the split 32 will return to tightlyabutting relation so as to effectively seal the valve opening againstleakage. In another aspect there is provided a means automaticallyoperable by the insertion of a nipple-equipped syringe tube into asocketed' portion on or associated with the bag wall, for

opening communication between the bag interior and the passage in thetube.

Although the invention in all of its aspects is not limited to theparticular type of connection between the receptacle and the syringetube 34, the preferred form of connection which is illustrated will befound quite advantageous, as the valve 29 is a self-closing valve, andno screw stopper or other closing device is required which may becomelost in the use of the article. It is only necessary to insert thenipple 33 in position within the valve to establish the properconnection of the tube 34 so as to adapt the device for use as asyringe, and likewise it is only necessary to withdraw this nipple andthe valve 29 will be self-sealing against leakage, and the device willbe ready for use as a hot water bag or ice bag.

Adjacent its lower end the wall of the bag It may be provided with athickened portion 35 through which an opening 36 is provided, so thatthe bag may be suspended from a nail, hook or the like, the opening 36through the side wall of the bag communicating with an opening or slot31 formed in the bottom or lower edge of the bag, also within thethickened portion 35. In case a hook is used, the free end thereof maybe accommodated in the slot 31. This provision obviates the necessity ofany projecting tab or the likev which would not conform to the lines ofthe bag itself.

Our improved bag as herein shown has a neat, attractive appearanceinasmuch as when closed it presents the shape of a shallow rectangularbody with rounded corners and rounded edges. The bag is streamlined asdistinguished from one having unsightly projections, and yet it hassatisfactory leak-proof closure means, syringe-tubeconnecting means, andsuspension provisions.

While we have shown and described a preferred embodiment of ourinvention, it will be understood that it is not to be limited to all ofthe details shown, but is capable of modification and variation withinthe spirit of the invention and wihin the scope of the appended claims.
